How to Make an Indoor Grow System


Starting plants from seed, or growing special flowers, is easy with an indoor grow system. Select a room or space where you can optimize moisture and drainage while minimizing the mess. Replace daylight with grow lights and use a mini greenhouse to surround your plants with moisture. It's not difficult to create an indoor grow system designed to nurture any kind of botanical.

Step 1

Design your growing tables to fit around plastic tray inserts that you can fill with plants or seed trays. Measure your trays and build a wooden frame slightly larger for easy removal. Build your grow table with one or two planting shelves, or with a planter on top and a storage shelf underneath.

Step 2

Make the wooden frames to hold the plastic trays. Cut two treated plywood sheets to fit your tray, with 1 inch added to both the length and the width. Cut four 6-inch-wide treated wood boards to fit the length and four to fit the width of your cut plywood.

Step 3

Attach the 6-inch-wide boards around the perimeter of your plywood with wood glue to make the sides of your indoor planter. Insert finishing nails every 2 inches to secure the sides in place.

Step 4

Cut four 6-by-1 inch boards to fit the desired height of your planter. Attach one leg to each of the four corners of the wooden planters, spaced as best suits your needs.

Step 5

Hang grow lights from a ceiling hook above the indoor planters to simulate daylight.

Step 6

Purchase or make small greenhouses to cover any plants that benefit from added moisture. Simply cover your pots with plastic sheeting suspended from wire hangers, or construct mini greenhouses from PVC pipe and plastic.
